Which term describes the process of gas turning into a liquid?

• A. Vaporize
• B. Liquefy
• C. Condense
• D. Depressurize

Answer: (C)

Gas turning into a liquid is called condensation. It happens when a gas loses enough energy (by cooling or by being compressed) so its molecules move more slowly and are drawn together by their attraction, forming a liquid. You can see condensation in fog or dew, and in air conditioning when water vapor in the air condenses on cooler surfaces. Vaporize describes the opposite change—liquid to gas. Liquefy means to turn something into a liquid, but condensation specifically names the gas-to-liquid transition due to energy loss. Depressurize lowers pressure and doesn’t by itself describe forming a liquid from a gas.
